Note:
Because of the ultra-high speed of the P4C1298, care must be taken
when testing this device; an inadequate setup can cause a normal
functioning part to be rejected as faulty. Long high-inductance leads
that cause supply bounce must be avoided by bringing the V
and
ground planes directly up to the contactor fingers. A 0.01 μF high
frequency capacitor is also required between V
and ground. To avoid
signal reflections, proper termination must be used; for example, a 50
test environment should be terminated into a 50
load with 1.73V
(Thevenin Voltage) at the comparator input, and a 116
resistor must
be used in series with D
OUT
to match 166
(Thevenin Resistance).
